This encryption happens with user specific encryption keys, so transfering this information by means to other accounts will not decrypt these, only the intended account sessions can read this information. You info is tightly secured.

Communication Code

Strangers can not contact you, can not add you to groups, can not call you, communication code is a 4 digit code thats generated by your app and the same is required for anyone trying to reach you, they can connect you only if they enter the code of yours.
